The LCM of 805,690,495,943,790 is 516264210.
Find LCM of 805,690,495,943,790 with Prime Factorization
| 2 | 805, 690, 495, 943, 790 |
| 3 | 805, 345, 495, 943, 395 |
| 5 | 805, 115, 165, 943, 395 |
| 23 | 161, 23, 33, 943, 79 |
| 7, 1, 33, 41, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 7 x 1 x 33 x 41 x 79 = 516264210
Therefore, the lowest common multiple of 805,690,495,943,790 is 516264210.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
805 x 690 x 495 x 943 x 790 = 204827825317500
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
805 : 1, 5, 7, 23, 35, 115, 161, 805
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
943 : 1, 23, 41, 943
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,690,495,943,790, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
690:2x 3x 5x 23
495:3x 3x 5x 11
943:23x 41
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 5x 23x 23 = 396750
Therefore, the value for common factors is 396750.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 204827825317500/(1x396750)
LCM = 204827825317500/396750
LCM = 516264210
Thus, we can understand that the LCM of 805,690,495,943,790 is 516264210.
